Sony 300mm f/2.8 G SSM II lens review: second update to pro-oriented G-series super-telephoto prime

With a DxOMark score of 24 points mounted on a Sony SLT Alpha 99, the Sony 300mm f/2.8 G II is a good performer but it’s not outstanding which is a surprise for a high-end (and high value) lens like this. Sharpness is somewhat disappointing at 15P-Mpix, given the theoretical maximum of 24P-MPix on the A99. As for Transmission, Distortion and Vignetting this lens performs very well indeed, while Chromatic Aberration is still low for a fast aperture telephoto (but still not the best in class).

Sorry - I have to doubt the result of this test...
I wrote this text und the list of Sony lenses tested HERE:
from my rather long experience with the predecessor, the still "current" 300/2.8 SSSM, there has to be a mistake in the testing of the new Sony lens - it will not be worse than the old version (or will it?).
And the current 300/2.8 SSM is at least on par with the Zeiss 85/1.4 AF or the 135/1.8 AF which I use, and a lot (and I mean: A LOT!) sharper than the Sony 35/1.4, for example - it is one of or even the best lens(es) in the Sony system. For an impression, just look at Sony´s MTF charts.
Almost everybody in the Sony forums who has access to that lens says the same... - so could there have been a mistake in the testing?
A focus problem or a "faulty" lens, for example?
I would LOVE to see a retest with a second item - Sony company should be interested in putting the result right and proving the 300/2.8 SSM to be the "stellar" lens it is... - the current version is indeed!

Thanks for your interest in DxOMark.
Sony lenses we analyzed were provided by Sony itself. About your remark on the 35mm f/1.4, analyzer results confirm what you noticed (please check the comparison here Sony 300mm vs 35mm f/1.4).
If you only look at the Sharpness score, the 300mm is far higher rated than the 35mm f/1.4. However the DxOMark score is performed lowlight. In such condition, the larger aperture of the Sony 35mm f/1.4 enables a lower noise on the SLT A99 sensor. That means that you will finally get a similar IQ on both couples: on one side (300mm), you have a sharp image but with an higher level of noise, on the other side, the image is softer but without noise.
